Specification of Letters Patent. Annlication filed September 15, 1905.Renewed January 31, 1907. Serial Patented Mareh 5, 1907 To all u-/1 0/,it may (:rn'wern:

Be it known that I, OTTO PFANDER, a sub-. ject of the German Emperor,residing. at Brussels, in the Kingdom of Belgium, have invented certaiiinew and useful Improvements in or Relating to Gear-Cases forMotor-Vehicles and the Like.

' This invention relates to an improved casing for inclosing thepower-transmission devices of automobiles,\bicycles, and the like andhas for its object the provision of a i' fgid casing of this characteradapted to be mounted u on operating and revoluble parts of the mecanism and permitting adjustment of the transmission device.

In the drawings, Figure 1 is alongitudinal section of a casing embod ingthe main features of my invention. ig. 2 is a sectional view taken online 2 2 of Fig. 1.

As shown in the drawings, A designates the driving-shaft, and B thedriven shaft, of

an automobile on which is mounted a su porting-wheel B. The hub of saidwheel is provided with a flange b, to which is se-. cured one of thesprocket-wheels b b means of bolts b assing through a flange Between theange b and the main body of the wheel I) is provided a cylindricalportion b adapted to receive one side of the improved casing in a manner'to be hereinafter de scribed. On the driving-shaft A is mountedasprocket-whee la and one member of a ballbearing of, the oth'ermember ofwhich is seated in a flange i, which latter is in turn rigidly securedin the bore of the hub h of a revoluble member g. Said member 9 isprovided With an extension having a polygonal ortion 7' and-a flange 7c.Said flange k a uts against and is p'referabl of the same diameter asthe flange m of a caring n, which latter is rigidly secured to the frameq of'the vehicle. The bore of said revoluble member is eccentricallydisposed with respect to its peripher so that when a wrench is appliedto the po ygonal portion 9' to turn the revoluble member the shafts Aand B are adjusted relatively to each other. This adjustment is effectedby means of a tension-rod, preferably comprising two s lit ortions a andI), the forward ends of w llCll ave a receiving-bearingffor therevoluble member 9 and j the rearward ends being mounted at (1 upon apart a of the driven shaft B. The tension-rod is preferably ri id, sothat as the revoluble member IS a justcd theshafts'A and B are isplaced.Indexes z and 3 are mounted on the flanges m and 70, respectively, toindicate 1 the relative position of the two flanges.

Any suitable means may be employed to anchor the revoluble member ginits adjusted positions-such, for instance, as is shown in my copendingapplication filed September 15, 1905, Serial No. 278,600.

The casing comprises inner and outer walls, the inner wall if beingmounted upon a casebearing shoulder a at the forward end and upon asimilar case-bearing shoulder 12 at the rearward end of the tension-rod.The

outer wall of said casing overhangs the shaft A and bears upon thecylindrical ortion b of the reaisprocket-wheel, whic bearing member may,if desired, be provided'with packing :12. 'lj'he tension'm'exn er isclamped 111 place by bolts 0. b

affecting the casing inclosing the same. j

I declare that what I claim isl. A casing for transmission devices com--in combination, an axle, a drivingshaft, a spacing or tension rodrevolubly. mounted on said axle and provided With'an annularcase-bearing shoulder concentric prising with said axle, the oppositeend of said rod being revolubly mounted on said shaft and provided withan annular case-bearing shoulder, and a casing'mounted on sai shoulders.

2. A casing for transmission devices comprising in combination, an axle,a drivin shaft, a spacing or tension rod revolubly mounted on said axleand provided annular shoulder concentric with-the axle, the, oppositeend of said rod carrying a revorom the foregoing it. will'be obviousthat the construction hereinj set forth provides for any desiredadjustment of theiension member without in any way;

with an lubly-mounted member eccentrically apertured and adapted toreceive the drivingshaft and also provided with an annular shoulderconcentric with said member, a casing mounted on said shoulders andadapted to close said device, and means for efl'ectj ing adjustment oftlie revoluble member.

3. A device of the class described com I prising in combination an axle,a drivin shaft, s acing or tension means for said sha t and ax c, and acasing mounted on said tension means.

4. A device of the class descrrbed com- )IlSlD in combination an axlefa-drivin I h J shaft, spacing or tension means for said, sha t and axlehaving case-bearing shoulders, and

'a casing mounted on said-shoulders.

-5. A device of the class described comprising in combination an axle, adrivingshaft means comprising a revoiubie 5 adjustingmember, saidtension means havshaft, spacing or tension means for said and axis, saiding case-bearing shoulders, and casing sald shoulders.

? In testimony whereof I affix my signature i in presence of twowitnesses. I OTTO PFANDER. i Witnesses:
